Something like Pokémon Champions feels overdue at this point. Hopefully, it should help to make the Pokémon competitive scene to be more accessible. I have a few friends who enjoyed the completive scene during the 3DS era, but lost interest in playing through the campaigns of the newer entries. This could potentially get them back into the series.
Legends Z-A looks good from what they showed, but there wasn't anything that particularly "wowed" me. I ended up skipping the first Legends game, so I'll probably want to go back and play that first before I consider getting the new one.
